A block of mass m1 = 1.20 kg moving at v1 = 1.20 m/s undergoes a completely inelastic collision with a stationary block of mass m2 = 0.500 kg . The blocks then move, stuck together, at speed v2. After a short time, the two-block system collides inelastically with a third block, of mass m3 = 2.60 kg , which is initially at rest. The three blocks then move, stuck together, with speed v3. Assume that the blocks slide without...
